How does one take out lost motion between the Duo-Art stack and
the piano action?

If there is a way to adjust this without removing the stack over
and over again, I cannot see it.  If Mike Kitner mentioned it in
his monograph [1], I have not been able to find it.  Can it play
evenly if this has not been carefully done?

Any thoughts?
